Conveyor belt cleaner scraper blade and assembly

摘要

A replaceable conveyor scraping blade has a blade body extending lengthwise along a longitudinal axis. The blade body is produced from a material having a flexible, elastic quality. The blade body comprises a base portion, and intermediate portion, and a terminal end. The base portion is attachable to a tensioning device for biasing the blade body against a conveyor belt. The intermediate portion is generally arcuate and comprises a leading surface and a trailing surface. The leading surface extends upwardly relative to the base portion. The trailing surface is opposite the leading surface. It also extends upwardly relative to the base portion and has a scalloped surface when viewed in cross-section extending lengthwise along the longitudinal axis. The terminal end has a scraping surface separating an uppermost portion of the trailing surface from an uppermost portion of the leading surface.

主权项

1. A replaceable conveyor scraping blade comprising:
a unitary blade body extending lengthwise along a longitudinal axis and produced from a material having a flexible, elastic quality comprising:
a base portion attachable to a tensioning device for biasing the blade body against a conveyor belt;a generally arcuate intermediate portion comprising a first surface extending upwardly relative to the base portion, and a second surface opposite the first surface, also extending upwardly relative to the base portion, and having a scalloped surface when viewed in cross-section taken transverse to the longitudinal axis and extending lengthwise along the longitudinal axis wherein the scalloped surface comprises a plurality of alternating convex and concave sub-surfaces, wherein a scraping surface is formed between the first and second surfaces having a variable contact angle, and wherein the alternating convex and concave surfaces provide a variable contact area which smoothens out peaks and valleys of a mechanical pressure application by providing slight variations in the contact area during blade wear; anda terminal end having a scraping surface separating an uppermost portion of the second surface from an uppermost portion of the first surface.
